Abstract (en)
[origin: EP3275531A1] A filter medium (20) includes a first porous polytetrafluoroethylene membrane (11), a first air-permeable support member (12), a second porous polytetrafluoroethylene membrane (13), and a second air-permeable support member (14). A surface of the filter medium (20) is formed by the first porous polytetrafluoroethylene membrane (11). A bond strength (A 1 ), as measured by a 180° peel test, between the first porous polytetrafluoroethylene membrane (11) and the first air-permeable support member (12) is higher than 1.2 N/25 mm and higher than a bond strength (A 2 ), as measured by the 180° peel test, between the first air-permeable support member (12) and the second porous polytetrafluoroethylene membrane (13).
